KSP PERFORMANCE 2" Wheel Spacers 6x5.5 (6x139.7) 78.1mm Hub Bore — Forged 6061-T6, Black Anodized (Pair)

KSP PERFORMANCE 2" forged wheel spacers widen the track of compatible GM trucks and SUVs to improve stance, clearance, and wheel fitment while retaining hub-centric alignment.

These 2-inch wheel spacers are engineered for late-model Chevy and GMC full-size pickups and SUVs that use the 6x139.7 (6x5.5) bolt pattern. Machined from 6061-T6 aluminum and hard-anodized for weather resistance, they come as a pair with high-strength studs and hardware to replace your factory wheel mounting surface and move the wheels outward by 2 inches per side.

Which vehicles and wheels are these spacers compatible with?

They match the 6x139.7 bolt pattern and a 78.1mm hub bore, making them suitable for many Silverado 1500, Sierra 1500, Tahoe, Yukon, Escalade, Suburban and related GM models across multiple years. Confirm your truck’s bolt pattern and hub bore before purchase to ensure proper fit.

• Bolt pattern: 6x139.7 (6x5.5)
• Thread pitch: M14 x 1.5
• Hub bore: 78.1 mm (3.07")
• Vehicle fitment includes Silverado/Sierra 1500, Tahoe, Yukon, Escalade, Suburban, Avalanche, Express, Savana

How are these spacers constructed and what hardware is included?

The spacers are CNC-machined from 6061-T6 aircraft-grade aluminum for an excellent strength-to-weight ratio, then hard-anodized to resist corrosion. Each kit includes forged aluminum spacers, heat-treated SCM435 studs and high-grade bolts with a thread locker for secure fastening.

• Material: 6061-T6 aluminum spacer, SCM435 studs
• Finish: black anodized surface for corrosion resistance
• Hardware: ISO/DIN 10.9–12.9 grade bolts and thread locker included
• Recommended torque: 85–95 ft·lb

What performance or fit changes can I expect after installation?

By moving the wheel outward 2 inches, you increase track width which can improve lateral stability and allow wider tires or different offset wheels without rubbing. You’ll also achieve a more aggressive wheel stance and additional brake or caliper clearance on many setups.

• Track increase: +2" per side (wheel sits farther from hub)
• Allows lower-offset or wider wheels and tires
• Possible improved visual stance and tire clearance
• Hub-centric design reduces runout and vibration risk

How difficult is installation and what should I check afterward?

Installation is straightforward with basic shop tools and a torque wrench; follow factory torque sequence and the kit’s recommended torque. After mounting, re-torque after a short test drive and check for proper wheel-to-spacer contact and absence of interference.

• Tools needed: torque wrench, jack, lug wrench
• Follow torque spec: 85–95 ft·lb
• Re-check torque after initial drive
• Verify wheel clearance and hub fitment

Who this is for: These spacers are aimed at owners of compatible GM full-size trucks and SUVs who want a wider stance, need extra clearance for larger wheels or brake upgrades, or prefer an enhanced visual profile. They suit DIY-savvy enthusiasts and professional installers who require a durable, hub-centric spacer with reliable hardware and corrosion-resistant finish. Always verify bolt pattern, hub bore and stud thread before purchase and consult a professional installer if unsure.
